A small plate is provided on the side of the reset plate 405. This small plate moves downward to contact the side of the card plate 402 and push the card plate 402 outward; the top rod Ⅰ406 is fixedly installed on the side of the upper end rod of the positioning plate 404; the round rod 407 is rotatably installed in the circular hole on the support frame 401;

[0038] like Figure 8-Figure 11 As shown, the half gear 409 is fixedly mounted on the round rod 407; the first ratchet 410 is rotatably mounted on the support frame 401, and the outer gear teeth of the first ratchet 410 are intermittently meshed with the gear teeth on the half gear 409. When the outer gear of the first ratchet 410 rotates counterclockwise, the inner shaft of the first ratchet 410 is driven to rotate counterclockwise; the gear I 411 is fixedly mounted on the round rod 407; the motor II 412 is fixedly mounted on the side of the support frame 401, and its motor shaft is fixedly connected to a gear, and the gear is meshed with the gear I 411; specifically, the motor II 412 is started, driving the gear I 411 to rotate, thereby driving the round rod 407 to rotate;

[0039] like Figure 8-Figure 11As shown, the cross bar 413 is slidably mounted on the inner side of the inner groove 103, a spring is mounted on the outer end of the cross bar 413, the other end of the spring is connected to the door body 101, and an annular groove cylinder is mounted on the outer end of the cross bar 413; the inner end of the support rod 414 is fixedly mounted on the inner end of the cross bar 413, the outer end of the support rod 414 is an inclined surface, and the inclined surface contacts the top rod Ⅰ406. When the top rod Ⅰ406 moves downward, the top rod Ⅰ406 pushes the support rod 414 to move outward, and the support rod 414 drives the cross bar 413 to move outward; the anti-pinch ball 415 is slidably mounted on the inner end of the cross bar 413 In the annular groove cylinder at the outer end of the cross bar 413, a spring is installed on the inner side of the anti-pinch ball 415, and the other end of the spring is connected to the outer end of the cross bar 413; the outer end of the bent rod 416 is fixedly installed on the side of the anti-pinch ball 415, and the inner end convex block of the bent rod 416 is intermittently in contact and squeezed with the upper end rod of the reset plate 405, that is, when the cross bar 413 moves outward and drives the anti-pinch ball 415 to move outward for a distance, the anti-pinch ball 415 drives the bent rod 416 to move outward, and at this time the inner end of the bent rod 416 moves to align with the upper end rod of the reset plate 405. When the clamping ball 415 is squeezed and moves into the annular groove cylinder at the outer end of the cross bar 413, the anti-clamping ball 415 drives the bent rod 416 to move into the annular groove cylinder at the outer end of the cross bar 413, and the inner end of the bent rod 416 squeezes the reset plate 405 to move downward; the support block 417 is fixedly installed in the inner groove 103; the reset rod 418 is slidably installed in the groove on the side of the support block 417, and a spring is installed on the reset rod 418, and the other end of the spring is connected to the side of the support block 417. The outer side of the reset rod 418 is an inclined surface, and this inclined surface is connected to the side of the support block 417. A push rod II 502 in a control mechanism 5 contacts, that is, the push rod II 502 in the control mechanism 5 moves downward, pushing the reset rod 418 to move in the direction close to the support block 417; the rack 419 is fixedly installed on the inner side of the reset rod 418; the vertical plate 420 is fixed on the side of the support frame 401; the second ratchet 421 is rotatably installed on the side of the vertical plate 420, and the outer teeth of the second ratchet 421 are intermittently meshed with the rack 419, and when the outer teeth of the second ratchet 421 rotate counterclockwise, the inner shaft of the second ratchet 421 rotates counterclockwise;

[0040] Specifically, when the door body 101 is fully opened, the motor II 412 drives the gear on its shaft to rotate counterclockwise, and this gear drives the gear I 411 to rotate clockwise, and the gear I 411 drives the round rod 407 to rotate clockwise for one circle. When the arc-shaped protrusion on the round rod 407 rotates to the upper end rod of the positioning plate 404 and squeezes and pushes the positioning plate 404 downward, the positioning plate 404 moves downward and drives the push rod I 406 to move downward, and the push rod I 406 pushes the support rod 414 to move outward. The support rod 414 drives the cross bar 413 to move outward, and the cross bar 413 moves outward to drive the anti-pinch ball 415 to move outward for a distance, and the anti-pinch ball 415 drives the bent rod 416 to move outward. At this time, the inner end of the bent rod 416 moves to align with the upper end rod of the reset plate 405. At this time, the anti-pinch ball 415 is located on the outside of the door body 101. At this time, the L-shaped plate at the lower end of the clamping plate 404 is clamped at the outer end of the clamping plate 402, so that the anti-pinch ball 415 is always located on the outside of the door body 101.

[0041] When the round rod 407 rotates one circle, the round rod 407 drives the half gear 409 to rotate one circle clockwise, and the half gear 409 drives the outer teeth of the first ratchet 410 to rotate 90 degrees counterclockwise, and the outer teeth of the first ratchet 410 drives the inner shaft of the first ratchet 410 to rotate 90 degrees counterclockwise. At this time, the inner shaft of the first ratchet 410 drives the cam 206 to rotate 90 degrees, so that the cam 206 rotates from a horizontal state to a vertical state. At this time, the cam 206 drives the two clamping rods II 207 to move outward at the same time, so that the outer ends of the two clamping rods II 207 are respectively clamped into the clamping holes on the inner sides of the outer ends of the two clamping rods I 203. At this time, the two clamping rods I 203 clamp the door body 101, so that the door body 101 cannot be manually closed;

[0042] When the pressing block 503 in the outer control mechanism 5 is manually pressed, the corresponding push rod II 502 brought by the pressing block 503 moves inward, and the push rod II 502 pushes the inclined surface on the outer side of the reset rod 418, and drives the reset rod 418 to move toward the direction close to the support block 417. At this time, the reset rod 418 drives the half gear 409 to move rightward, and the rack 419 drives the outer teeth of the second ratchet 421 to rotate counterclockwise, and the outer teeth of the second ratchet 421 drive the inner shaft of the second ratchet 421 to rotate counterclockwise, and the inner shaft of the second ratchet 421 drives the cam 206 to rotate 90°, so that the cam 206 rotates from the vertical state to the horizontal state. At this time, the cam 206 drives the two clamping rods II 207 to respectively disengage the control of the two clamping rods I 203, and then the motor I 105 is started to close the door body 101;

[0043] When the door body 101 is closed, the anti-pinch ball 415 will be stuck between the frame and the door body 101 to prevent the passenger's hand from being squeezed when the door body 101 is closed. When the anti-pinch ball 415 is squeezed and moves into the annular groove cylinder at the outer end of the cross bar 413, the anti-pinch ball 415 drives the bent rod 416 to move into the annular groove cylinder at the outer end of the cross bar 413, and the inner end of the bent rod 416 squeezes the reset plate 405 to move downward. At this time, the small plate on the side of the reset plate 405 moves downward and contacts the side of the card plate 402, and pushes the card plate 402 outward. The card plate 402 moves outward under the thrust. At this time, the card plate 402 is pushed outward. The lower end of 02 is no longer stuck to the L-shaped plate at the lower end of the locking plate 404. At this time, the spring at the lower end of the locking plate 404 releases the pressure to drive the locking plate 404 to move downward and return to its position. At this time, the locking plate 404 drives the top rod Ⅰ406 to move upward and return to its position, and the top rod Ⅰ406 no longer squeezes the support rod 414. At this time, the spring at the outer end of the cross bar 413 releases the pressure, pushing the cross bar 413 to move back and return to its position, and the cross bar 413 drives the anti-pinch ball 415 to move back and return to its position. At this time, the door body 101 will be completely closed. In this way, it is prevented from squeezing people's hands when the door body 101 is closed, and the anti-pinch of the door body 101 is achieved.

[0051] Working principle: The device can provide power for the opening and closing of the door body 101 through solar energy, effectively saving resource waste; the device can realize the automatic opening and closing of the door body 101, saving manpower and improving the sense of happiness in life; the device can buffer the door body 101 when the door body 101 is closed, preventing the door body 101 from pinching the hands when closing, and effectively ensuring the safety of passengers;

[0052] When the door 101 needs to be opened, the pressing block 503 of the inner control mechanism 5 is manually pressed. The pressing block 503 moves downward, driving the corresponding push rod II 502 to move downward. The push rod II 502 contacts the contact button on the inner side of the door 101. The contact button receives the signal and transmits the signal to the motor I 105 and the motor II 412. The motor I 105 receives the signal and starts, driving the two hinges 104 to work, thereby driving the door 101 to open. At the same time, the motor II 412 receives the signal and starts, and the motor II 412 drives the gear on its shaft to rotate counterclockwise. The gear drives the gear I 411 to rotate clockwise. The gear I 411 drives the round rod 407 to rotate clockwise for one circle. When the round rod 407 rotates one circle clockwise, the round rod 407 rotates one circle clockwise. The arc-shaped protrusion on the upper end of the card plate 404 rotates to the upper end rod of the card plate 404, and squeezes and pushes the card plate 404 downward, the card plate 404 moves downward to drive the top rod I 406 to move downward, the top rod I 406 pushes the support rod 414 to move outward, the support rod 414 drives the cross bar 413 to move outward, the cross bar 413 moves outward to drive the anti-pinch ball 415 to move outward for a distance, the anti-pinch ball 415 drives the bent rod 416 to move outward, at this time the inner end of the bent rod 416 moves to align with the upper end rod of the reset plate 405, at this time the anti-pinch ball 415 is located on the outside of the door body 101, at this time, the L-shaped plate at the lower end of the card plate 404 is stuck at the outer end of the card plate 402, so that the anti-pinch ball 415 is always located on the outside of the door body 101;

[0053] When the round rod 407 rotates one circle, the round rod 407 drives the half gear 409 to rotate one circle clockwise, and the half gear 409 drives the outer teeth of the first ratchet 410 to rotate 90 degrees counterclockwise, and the outer teeth of the first ratchet 410 drives the inner shaft of the first ratchet 410 to rotate 90 degrees counterclockwise. At this time, the inner shaft of the first ratchet 410 drives the cam 206 to rotate 90 degrees, so that the cam 206 rotates from a horizontal state to a vertical state. At this time, the cam 206 drives the two clamping rods II 207 to move outward at the same time, so that the outer ends of the two clamping rods II 207 are respectively clamped into the clamping holes on the inner sides of the outer ends of the two clamping rods I 203. At this time, the two clamping rods I 203 clamp the door body 101, so that the door body 101 cannot be manually closed;

[0054] When the pressing block 503 in the outer control mechanism 5 is manually pressed, the corresponding push rod II 502 brought by the pressing block 503 moves inward, and the push rod II 502 pushes the inclined surface on the outer side of the reset rod 418, and drives the reset rod 418 to move toward the direction close to the support block 417. At this time, the reset rod 418 drives the half gear 409 to move rightward, and the rack 419 drives the outer teeth of the second ratchet 421 to rotate counterclockwise, and the outer teeth of the second ratchet 421 drive the inner shaft of the second ratchet 421 to rotate counterclockwise, and the inner shaft of the second ratchet 421 drives the cam 206 to rotate 90°, so that the cam 206 rotates from the vertical state to the horizontal state. At this time, the cam 206 drives the two clamping rods II 207 to respectively disengage the control of the two clamping rods I 203, and then the motor I 105 is started to close the door body 101;

[0055] When the door body 101 is closed, the anti-pinch ball 415 will be stuck between the frame and the door body 101 to prevent the passenger's hand from being squeezed when the door body 101 is closed. When the anti-pinch ball 415 is squeezed and moves into the annular groove cylinder at the outer end of the cross bar 413, the anti-pinch ball 415 drives the bent rod 416 to move into the annular groove cylinder at the outer end of the cross bar 413, and the inner end of the bent rod 416 squeezes the reset plate 405 to move downward. At this time, the small plate on the side of the reset plate 405 moves downward and contacts the side of the card plate 402, and pushes the card plate 402 outward. The card plate 402 moves outward under the thrust. At this time, the card plate 402 is pushed outward. The lower end of 02 is no longer stuck to the L-shaped plate at the lower end of the positioning plate 404. At this time, the spring at the lower end of the positioning plate 404 releases the pressure to drive the positioning plate 404 to move downward and return to its position. At this time, the positioning plate 404 drives the top rod Ⅰ406 to move upward and return to its position, and the top rod Ⅰ406 no longer squeezes the support rod 414. At this time, the spring at the outer end of the cross bar 413 releases the pressure, pushing the cross bar 413 to move back and return to its position. The cross bar 413 drives the anti-pinch ball 415 to move back and return to its position. At this time, the door body 101 will be completely closed; in this way, it is prevented from squeezing the hands of the people when the door body 101 is closed, and the anti-pinch of the door body 101 is realized;

[0056] In addition, the solar panel 301 converts solar energy into electrical energy through the photovoltaic effect, and stores the electrical energy in the charge controller 302. The charge controller 302 converts the electrical energy and then enters the battery pack 303 for storage. Then, the battery pack 303 provides power to the motor I 105 and the motor II 412, so that the entire power consumption of the equipment is provided by the solar panel 301, which effectively saves resource waste and has great development prospects.
